About us
ARCHI is a two-person product design studio.
We design products, we write code, and we ship features. Real ones: merged PRs, not prototypes gathering dust in Figma. Over the past three years, we've worked with 30+ founders on products that have raised over $1B from top-tier investors.
We named the studio ARCHI because what we do is closer to architecture than decoration. Architects decide where the load-bearing walls go. They design the structure everything else gets built on top of. That's the work we care about. Anyone can move a button. Very few people can decide what your product is, build the system that lets your team express it consistently, and leave behind something that holds up as the company grows.
Lately, our role has expanded past the canvas. Design is still our craft, but we now also write production code, prototype in real components, and build the AI workflows that let small teams move fast.
Need an MVP shipped before your next fundraise?
A product redesign that actually gets implemented?
A small fast team that does product strategy and pull requests in the same week, in or alongside yours? That's us.

Qonto — All business finances, in one app
Qonto is the business banking app used by 600,000+ European companies. Over a three-year engagement, we led the onboarding — constantly refining step order, running A/B tests, and pushing conversion on a flow that’s inherently long, where every second saved translates directly into more accounts created. We also led card management — from ordering to Apple Pay enrollment to spending controls that reduced card-related support tickets by 20% — the dashboard that gave companies their first real cash flow visibility, the dark mode rollout with full accessibility compliance, and a design system built to scale across cross-functional teams.
